The soft, earthen colors are the unmistakable sign of authentic vegetable dyes: colors not found in modern Scottish tartans. Welsh sheep have long guard hairs in their wool. The resulting 'kemp hair' fleeces are rough, but if finished correctly in the 'Pandy' i.e., boiled, steamed and pressed, the best of them produced blankets of exceptional warmth and wear resistance, akin to a fine felt.

"Tair swydd iaith: adrawdd, cynhyrfu a ddyfalu" which can be translated literally as "three offices of language: describing, exciting [emotion] and imagining" is one of the Welsh Triads.

The Triads, found in various medieval manuscripts, are collections of historic facts, mythological traditions, moral maxims, or rules of poetry organized in groups of threes. It is believed that they evolved in the bardic schools as mneumonic devices to assist in the learning of narrative material.

Many of the triads contain Arthurian references. For a more complete discussion of them, as well as many more examples, see Gordd Cymru The Welsh Triads
